IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 206,817, dated August6, 1878 application filed January 23, 1878.

To all whom it may concern:

Be it known that I, JOSIAH Oornounr, of Minneapolis, in the State ofMinnesota, have invented certain new and useful Improvements 1n SpringBed-Bottoms; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of. this specification.

The nature of my invention consists in the construction and arrangementof a spring bedbottom, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, Iwill now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view ofmy improved spring bed-bottom arranged in abedstead. Fig. 2 1s a longitudinal vertical section of the same. Fig. 3is an enlarged rear elevation of a portion of the bed-bottom. Fig. 4shows a port1on of the bedstead. Figs. 5, 6, and 7 are detailed "iews ofparts of the bed-bottom.

A represents a bedstead of any suitable construction, provided with legsB B at each end, which are connected by a round, a, and pivoted to theside rails of the bedstead. These logs are held in position by means ofpivoted latches b, as shown fully in Fig. 4. These latches, when inposition to hold the legs, form part of a strip, 0, secured lengthwiseon the inner side of each side rail of the bedstead. Along the loweredges of the head and foot boards are secured similar strips d d, whichare, however, in a plane below that of the strips b b.

The bed-bottom is composed of, first, a frame consisting of twolongitudinal bars, b 0, connected by means of a series of cross-bars, DD, fastened on top of them. When this frame is placed in the bedstead Athe ends of the bars C 0 rest upon the head and foot board strips d 02,while the ends of the cross-bars D D rest upon the side rail strips 12b, and the bedbottom thus obtains a firm support in every direction. Thebars 0 and D are fastened together by means of staples e e, the arms orends of which are passed downward through proper holes made for them,and there clinched on the under side. In the center on top of each bar 0is fastened a block or shoe, E, and on top thereof is fastened a woodenspring, G. These parts are also united together by staples in the samemanner as described for the frame 0 D. The springs G G are fastened inthe center, and their ends are passed through staplesf, which arefastened in and project from the under sides of two cross-bars, I I, oneat or near each end of the bed-bottom. The cross-bars I I support aseries of bed-slats, H H, which are at one end secured to one cross-barby staples clinched on the under side, and at the other end the slatspass through elongated staples h h, fastened on top of the othercross-bar, I. Under each slat H is placed a series of spiral springs, J,resting upon the cross-bars D of the bottom. At the head the ends of thewooden springs G rest upon spiral springs J, which are supported uponthe ends of the longitudinal bars 0. At or near the center of thebed-bottom the slats H are connected in pairs in the following manner:The outside slat on each side is on its un der side provided with anarm, K, which two arms connect with cranks i i on the ends of a shaft,L, which is placed in suitable bearings on the under side of the bars 0O of the bottom frame. The second slat on each side is in like manner,by rods or arms K, connected with a second crank-shaft, L, and so on inrotation, according to the number of slats in the bed. These devicesform equalizers, so that the weight on oneside of the bed-bottom willact on the other side in the same manner. The arms K K are by staplesconnected to small blocks 7:, and these are in turn by staples connectedto the under sides of the bed-slats. This bed-bottom is provided with ahead-rest composed of a series of short slats, P, connected near theirupper ends by means of staples to a cross-bar, It. The lower ends of theslats P are hinged to the top of the bed-slats H bymeans of staples m a.A staple, m, is passed through each slat H and clinched on the underside. Two staples, a n, are passed through the staple m, and one arm ofeach staple a laid an gularly outward on top of the inner end of theslat P, and then passed through said slat to the under side, where it isclinched 1) attached to the bars (I.

with the end of the other arm of the same staple, as shown. Thecross-bar R of the head-rest is, near each end, prot'ided with a pendentarm, S, loosely connected thereto by staples, said arms passing downthrough holes in the ends of the outer slats H and through staples Ontop of the slats H, near the head end, in suitable hearings, is placed ashaft, 1, Figs. 2 and 3, having two cords or chains, 8 8, attached toand wrapped around the same, the ends of said cords or chains beingfastened to the lower ends of the arms S S. The shaft 1* is at one endprovided with a crank, V, by means of which it may be rotated, thus, bythe winding up of the cords s, raising the arms S and adjusting thehead-rest to any height or angle desired.

It will be noticed that in the construction of this entire bedbottom nonails or screws JOSIAH OOTHOUDT.
